WebApr 26, 2016 · I just started out with Chisel and wrote a simple counter to blink an led. The FPGA board (Lattice iCEstick) has an inverted reset signal, and instead of changing the polarity in the generated verilog, I want to set it in Chisel. I found that Module has a _reset parameter of type Chisel.Bool that can be set to false which inverts the reset signal.

"Chisel/FIRRTL: Reset Reset As of Chisel 3.2.0, Chisel 3 supports both synchronous and asynchronous reset, meaning that it can natively emit both synchronous and asynchronously reset registers. The type of register that is emitted is based on the type of the reset signal associated with the register.

WebChisel Data Types. Chisel datatypes are used to specify the type of values held in state elements or flowing on wires. While hardware designs ultimately operate on vectors of binary digits, other more abstract representations for values allow clearer specifications and help the tools generate more optimal circuits. WebApr 21, 2015 · Note: that in Chisel 3.2 the top-level abstract reset would always be set to synchronous reset. In Chisel 3.3.0, two traits were added: RequireSyncReset and RequireAsyncReset. These can be used to change the reset type of the register connected to regAbstract from synchronous to asynchronous.
